1 mmThis was the right answer

The large-vehicle requirement is at least 1 mm across three-quarters of the tread breadth, in a continuous band around the whole circumference. Goods vehicles of 3.5 tonnes or less generally use the separate 1.6 mm standard. Correct pressure and freedom from defects also matter.
